Morthos quickly recovered. He saw that Kaelen's sacrifice had broken the stability he needed. He raised his staff, aiming a blast of dark magic at Kaelen and Lyra.
"You fool! You have broken the balance! I will destroy you both, and then I will rebuild the Nexus on the ashes of your kingdoms!"
Lyra was still weak, but Kaelen's touch gave her strength. Her mind worked fast, combining the True Prophecy with Morthos's captured secrets.
"The Nexus needs the two crowns, Kaelen!" Lyra shouted, her voice shaking. "It needs the Iron Crown and the Sunstone Amulet! Our father's message! They must be combined!"
Kaelen looked up at the dais where the Iron Crown of Aethelgard rested, a heavy, jagged circle of cold iron. It was the symbol of his authority, his discipline, and his sorrow.
"Morthos, stop!" Kaelen roared, pushing Lyra behind him. He ran to the dais, ignoring Morthos's blasts of dark magic that chipped the marble around him.
Kaelen grabbed the Iron Crown. He ran back to Lyra.
Lyra, still weak, held the Sunstone Amulet—a vibrant, golden ball of light. It was the symbol of Sol's magic, healing, and warmth.
"The Iron must meet the Sun!" Lyra whispered. "Together, they do not create stability for Morthos. They create true balance for us!"
Kaelen, burned and bleeding, held the Iron Crown high. He brought the heavy, cold metal down, surrounding the warm, glowing Sunstone Amulet.
As the Iron Crown touched the Sunstone Amulet, a massive, blinding flash of pure white light erupted. It was not the gentle gold of Lyra's healing, nor the dark purple of Morthos's chaos. It was the perfect, terrifying Union of the two kingdoms.
The light struck Morthos. The traitor screamed, a sound of pure agony. His dark magic, which thrived on imbalance, was destroyed by the perfect harmony. The Nexus shattered. Morthos's body dissolved into dust, and his black robes fell onto the marble floor. The powerful, ambitious mage who had manipulated two kingdoms was gone.
The immense light faded, leaving Kaelen and Lyra standing in the Hall of Ancestors, breathing heavily, their bodies exhausted, but their hearts finally free. The war was over.
